Edexcel chemistry grade boundaries are really high especially unit 5. seriously like wtf 80 out of 90 for an A*, 74 out of 90 for an A (which is a mark greater than he A* grade boundary for june 2012, 2011 and 2010). Are they on meth or something? can someone please tell me that i'm not overreacting because although it was a long time ago, the exam wasn't anymore difficult or easier than previous summer exams. i mean ffs edexcel, you ruin everything

I feel biology edexcel is also pretty high unit 5! I think edexcel have yet again screwed me over!

UMS boundaries always remain the same, it is the grade boundaries or raw marks that alter. E.g. in a paper out of 100 UMS, it will always be 80 UMS for an A. If that paper is 75 raw marks, it can vary between approximately 55-65 for an A depending on the difficulty of the paper. Look at past grade boundaries to see whether they are high or low
